Windows下VScode快速配置OpenCV开发环境 【快乐篇】

时间：2024-10-03 07:05:10

1.前言

由于业务需要本人通过vscode快速迭代配置了一版OpenCV的开发环境，因为要快所以直接用大佬们构建好的openCV就行。本人这里是64位的Window11下配置的。

2.前置工具

vscode IDE工具

3.安装VScode插件

  1. C/C++
  2. C/C++ Extension Pack
  3. C/C++ Themes
  4. CMake
  5. CMake Tools

4.配置需要的OpenCV，Mingw,CMake等三个环境变量配置

4.1选择OpenCV-4.5.2-x64 | zip | tar.gz版本

github地址:GitHub - huihut/OpenCV-MinGW-Build: ???? MinGW 32bit and 64bit version of OpenCV compiled on Windows. Including OpenCV

4.2 安装MinGW-x86_64-8.1.0-posix-seh-rt_v6-rev0

官方下载地址:MinGW-x86_64-8.1.0-posix-seh-rt_v6-rev0

4.3.安装配置CMake-3.18.4

github地址:Releases · Kitware/CMake · GitHub

4.2 将压缩包统一解压到D:/Operating-Environment/目录下,其他环境配置同理

5.VScode中运行程序

5.1 示例代码main.cpp和图片：

#include <iostream>
#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;

int main() {
    string imagePath = "./test.png"; // 确保路径正确
    cout << "Loading image from: " << imagePath << endl;

    Mat image = imread(imagePath);
    if (image.empty()) {
        cerr << "Error: Could not open or find the image at " << imagePath << endl;
        return -1;
    }

    imshow("Display Image", image);
    waitKey(0);
    return 0;
}

5.2 配置c_cpp_properties.json

5.2.1按F1选中C/C++配置项

5.2.1修改C/C++配置

5.2.2 C/C++配置代码json
{
  "configurations": [
    {
      "name": "Win32",
      "includePath": [
        "${workspaceFolder}/**",
        "D:\\Operating-Environment\\mingw64\\include"
      ],
      "defines": [
        "_DEBUG",
        "UNICODE",
        "_UNICODE"
      ],
      "compilerPath": "D:/Operating-Environment/mingw64/bin/g++.exe",
      "cStandard": "c17",
      "cppStandard": "c++17",
      "intelliSenseMode": "gcc-x64"
    }
  ],
  "version": 4
}

5.3 配置tasks.json

5.3.1按F1选中Tasks:Configure Default Build Task

5.3.2 将创建的模板替换成下面那个，环境路径要对应自己的
{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "shell",
			"label": "debug",
			"command": "D:/Operating-Environment/mingw64/bin/g++.exe",
			"args": [
				"-fdiagnostics-color=always",
				"-g",
				"${file}",
				"-I", "D:/Operating-Environment/OpenCV-MinGW-Build-OpenCV-4.5.2-x64/include",  // 包含路径   头文件   编译的时候到这个路径下找头文件  编译审生成可重定位文件
				"-L", "D:/Operating-Environment/OpenCV-MinGW-Build-OpenCV-4.5.2-x64/x64/mingw/bin", // 库路径   动态链接库地址，可执行文件运行起来需要这些库提供的机器码
				// "-l","libopencv_world4100",           // 链接需要使用这些dll作为可重定位文件
				"-l","libopencv_calib3d452",
				"-l","libopencv_photo452",
				"-l","libopencv_core452",
				"-l","libopencv_stitching452",
				"-l","libopencv_dnn452",
				"-l","libopencv_video452",
				"-l","libopencv_features2d452",
				"-l","libopencv_videoio452",
				"-l","libopencv_flann452",
				"-l","libopencv_gapi452",
				"-l","libopencv_highgui452",
				"-l","libopencv_imgcodecs452",
				"-l","libopencv_imgproc452",
				"-l","libopencv_ml452",
				"-l","opencv_videoio_ffmpeg452_64",
				"-l","libopencv_objdetect452",
				"-o",
				"${fileDirname}\\${fileBasenameNoExtension}.exe"
			],
			"options": {
				"cwd": "D:/Operating-Environment/mingw64/bin"
			},
			"problemMatcher": [
				"$gcc"
			],
			"group": {
				"kind": "test",
				"isDefault": true
			},
			"detail": "compiler: D:/Operating-Environment/mingw64/bin/g++.exe"
		}
	]
}

5.4 配置launch.json

5.4.1 选择run下面的 start Debugging创建launch.json模板

5.4.1 在默认生成的模板替换成我的

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [


        {
            "name": "(gdb) Launch",
            // "preLaunchTask": "g++.exe build active file",//调试前执行的任务，就是之前配置的tasks.json中的label字段
            "preLaunchTask": "debug",
            "type": "cppdbg",//配置类型，只能为cppdbg
            // "label": "C/C++: g++.exe build active file",
            "request": "launch",//请求配置类型，可以为launch（启动）或attach（附加）
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",//调试程序的路径名称
            "args": [],//调试传递参数
            // "args": ["/F","${fileDirname}\\${fileBasenameNoExtension}.exe","&","pause"],//调试传递参数
            // "stopAtEntry": false,
            "stopAtEntry": false,
            // "cwd": "${workspaceFolder}",
            "cwd": "${fileDirname}",
            "environment": [],
            // "externalConsole": true,//true显示外置的控制台窗口，false显示内置终端
            "externalConsole": false,//true显示外置的控制台窗口，false显示内置终端
            "MIMode": "gdb",
            "miDebuggerPath": "D:/Operating-Environment/mingw64/bin/gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            // "preLaunchTask": "g++.exe build active file",
            // "internalConsoleOptions": "neverOpen"
            // "preLaunchTask": "build",  // Ensure build task runs before launch
            "internalConsoleOptions": "neverOpen"
        }
    ]
}
5.4.1 点击运行就行

5.5 运行结果（真好看）

6.结语

自此结束了，累死我了，用了一天的时间进行配置。原图就送你们了。
